The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s happening at Jaconé.
Right off the bat, we’ve got a solid run of swell kicking off Monday morning the 7th. It’s not a small one, so this is for the crew who know what they’re doing. The water temp is sitting right on 73°, which is pretty much normal for this time of year, so no nasty surprises when you hit the water.
Monday morning the 7th sees a 8ft south swell rolling in with a period of 11 seconds, and the wind is dead glass from the SSW at just 3 mph. It’s going to be clean as a whistle. The combined energy is strong at 1579, so there’s plenty of grunt in the water. This is a standout session for the experienced surfer. Monday afternoon stays glassy with a light NNW breeze, swell dropping just a touch to 8ft from the SSW.
Tuesday the 8th is still a good call. Morning sees 5ft of south swell with an offshore breeze from the ENE at 6 mph, making for clean, lined-up waves. The energy is moderate at 873. Afternoon stays clean with a cross-offshore wind, swell holding at 5ft.
Wednesday the 9th starts with a glassy morning, 5ft of easterly swell but the period is a short 7 seconds, so it’ll be a bit bouncy and less powerful. The energy is moderate at 627. Still, with glassy conditions, it’s worth a paddle. The afternoon drops off to 3ft.
Thursday the 10th is a great call. The morning is clean with a 4ft south swell, long period of 12 seconds, and a light cross-offshore breeze. The afternoon is the real highlight: glassy conditions, 4ft south swell, still a 12-second period, and the energy builds to 667. This is classic, clean, long-period groundswell that will wrap in nicely.
Friday the 11th is another top pick. Clear skies, glassy morning, 4ft south swell with a very long period of 14 seconds. The energy is 678. That’s proper groundswell, and with glassy conditions, it’s going to be a joy. The afternoon stays clean with a cross-offshore breeze.
Now, Saturday the 12th takes a turn. The morning is a bit of a mess with a cross-onshore wind from the west at 9 mph, making for choppy conditions on a 5ft ENE swell. The afternoon is worse – a strong 19 mph south cross-onshore wind, dropping to 2ft. That’s a write-off.
Sunday the 13th is a beast, but only for the experts. We’re looking at a 10ft SSW swell with a 12-second period, and the combined energy is a massive 2715. That’s powerful. The wind is light cross-onshore in the morning, but the swell is too big for this break. This is a big-wave day for the chargers only.
Monday the 14th has a fresh offshore breeze from the NE at 19 mph, keeping the face clean on a 8ft SSE swell. The energy is still very strong at 2065. This is another one for the experienced crew. The afternoon holds similar conditions.
After that, the week settles into a more moderate, mixed bag. Tuesday the 15th morning is a write-off with onshore wind, but the afternoon turns glassy again with a 5ft SSE swell – a nice sneaky session.
Wednesday the 16th and Thursday the 17th are marginal, with light cross-offshore winds but not much size or consistency. Friday the 18th sees a pickup in energy, with a 7ft to 7ft south swell, long period of 14 seconds, and clean cross-offshore winds. The energy is strong at 1458 to 1775. This is a promising day for the experienced surfer.
Saturday the 19th is the next standout. Morning shows a clean 8ft south swell, 13-second period, with a moderate offshore breeze from the ENE at 16 mph. The energy is very strong at 2063. This will be a big, clean, powerful day. Afternoon stays clean.
Sunday the 20th backs off to 5ft with a gentle offshore breeze in the morning – a nice, manageable day for the intermediate crowd. The rest of the period into the 21st and 22nd fades into smaller, weaker swell with more cross-onshore or light winds, not offering much to get excited about.
So, to sum up the standouts: Monday morning the 7th and Thursday afternoon the 10th are the pick of the first week – glassy, clean, with proper south groundswell. For the second week, Saturday the 19th looks like a ripper for the experienced crew, with a strong, clean offshore swell.
Stay safe out there, and keep your eyes on the horizon.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
